Obama’s Unconstitutional War – By Bruce Ackerman | Foreign Policy

In taking the country into a war with Libya, Barack Obama’s administration is breaking new ground in its construction of an imperial presidency — an executive who increasingly acts independently of Congress at home and abroad. Obtaining a U.N. Security Council resolution has legitimated U.S. bombing raids under international law. But the U.N. Charter is not a substitute for the U.S. Constitution, which gives Congress, not the president, the power “to declare war.”

After the Vietnam War, Congress passed the War Powers Resolution, which granted the president the power to act unilaterally for 60 days in response to a “national emergency created by attack upon the United States, its territories or possessions, or its armed forces.” The law gave the chief executive an additional 30 days to disengage if he failed to gain congressional assent during the interim.
